Switch mechanism

My present invention reiateF to eiectric Switches of the liquid. time''type and para ticulariy to such a switch in which means is provided formoving the switch into the circuit breaking position or into the circuitmaking position through compi-ete mot/'oment from one position to theother 'Without possibility under normai conditions of the Switch ofstopping the switch at a. `criticai Position such as at a position inwhich spari? ing might occur in the making or incurring of the circuit.

it is an object of my invention to provino such a switch T.Vith simpiemovement niembers.,

it is also an object of .my invention to provide such a switch withcompact tiimena sione2 occupying a minimum amount oi space, and havingsimple operating parte. Further objects of my intention will appear fromthe. specification and drawing.

fitti 'Ihis application is a division of my copending application SerialNumber 741,080, filed October 1, 1924.

I claim:

l. In an electric switch mechanism, n liquid iow switch mounted forpivotal movement, a pivoted member having spr' toggle connection withsaid switch, an two nush buttons connected to said toggle through cumsurfaces and adapted to move said switch through seid spring toggle `ineither direction on its support respectively.

2. 1n an electric switch mechanism, a liquid How switch mounted forpivotal movement, e piroted member having sprin toggle connection withseid switch, an two push buttons connected to said toggle through camsurfaces and adapted to move said switch through seid spring toggle ineither direction on its su port respectively :ind means connecting suipush buttons for pushing the one out when the other is pushed 1n.

3. In un electric switch mechanism, e pivoted member, a. liquid flowswitch connected lthe other is beine to said member for movementthereby, n second pivoted member, toggle connection between said pivotedmembers, two push buttons having cam surfaces engaging second saidmember und adapted to move 1t one in a clockwise und the other in acounterclockwise direction respectively, und means for pushing one ofsaid push butt-ons out when pushed in.

4. In en electric switch mechanism, a pivoted member, a liquid iowswitch connecte to said member for movement thereby, a second pivotedmember, spring toggle connection between said pivoted members, two pushbuttons having cam surfaces engaging second said member and adapted tomove it one in e clockwise and the other in a counterclockwise directionrespectively; and means for pushing one of said push buttons out whenthe other is being pushed in.
